The 61-year-old former Chelsea coach's contract expires at the end of the tournament in Gabon.
"I came for two years in Ghana, we extended to two years and three months because we qualified for the Nations Cup," Grant told BBC Sport.
"I will always take good memories from here, but hopefully the last memory will be the best one."
Leading Ghana to the title in Gabon, and ending the Black Stars' 35-year wait to win the Nations Cup for a fifth time, would be a sensational way for Grant to sign off.
And it would help to ease the pain of losing on penalties to Ivory Coast in the final two years ago.
Grant's side are on track in Gabon and will book a quarter-finals place if they beat Mali in their second Group D match on Saturday, having defeated Uganda 1-0 in their opener.
Regardless of whether Ghana go all the way or contrive to fail to qualify from their group, Grant's comments appear to confirm he will soon be employed elsewhere.
Grant has been linked with job offers from China and Australia, but when asked what his next move will be Grant was non-committal.
He said: "I am happy with what I have achieved in my career.  In my life I never plan. What will happen, will happen. Let's see.
"I am looking forward myself to see what will happen."
Avram Grant has given a strong indication his time as Ghana coach will end after the Africa Cup of Nations.

The flat-pack specialist said profit in its 2013 financial year rose 3.1% to 3.3bn euros (Â£2.7bn), helped by strong growth in China, Russia and the US.
Global sales totalled 27.9bn euros, and the retailer repeated its aim to to make 50bn euros in sales by 2020.
"Consumer spending is improving," said Ikea president Peter Agnefjall.
Mr Agnefjall said sales in southern Europe, which is still suffering from the impact of the financial crisis, were now "showing good signs of activity".
"Europe in general is starting to recover," he added.
Ikea said large, emerging market countries were important sources for future growth.
The chain opened five new stores last year, two of which were in China.
It said it is now looking for the right location for its first Indian store.
The privately owned firm, known for its huge warehouse-like stores, now has 303 outlets globally.
Ikea, the world's largest furniture chain, made a record profit last year, increasing market share in almost all the countries it operates in.

Vern Cotter's men led until the last four minutes of their opening autumn Test before Tevita Kuridrani's try snatched victory for Australia.
The Scots play Argentina on Saturday and then Georgia a week later before a Six Nations opener against Ireland.
"We will take a lot of positives from the weekend," said Russell, 23.
"It was a good game against a very good team and we were ahead for a lot of the game.
"But there is a lot to learn about how to close out games with 10 minutes to go.  The play-makers and decision-makers will learn from that.
"If we get into the same situation against Argentina, we will do things differently, and hopefully with a different outcome.
"We have still got another two games before the Six Nations. But having such a tight game against Australia that we potentially should have won, we will definitely learn from that and we will be a better team come the Six Nations."
While Saturday's denouement at Murrayfield brought back painful memories of another one-point loss to the Wallabies at last year's World Cup, Russell does not believe there is any psychological barrier impeding the Scots
"Even when they scored the try I was still confident we could go down the other end and get a penalty or drop-goal or something," he said.
"Everyone is still gutted about it but the boys are generally pretty good at moving on.  You have got a game next weekend so you can't dwell on it too much. That is the good thing about sport.  You can make it right the next week.
"The boys are all smart enough rugby players to learn from it.  We all know what we needed to do.  We will look back over it, chat as a group and learn from it as a team. But I don't think we need the psychologists in."
Forwards coach Jonathan Humphreys was happy to highlight the many positive aspects of Scotland's display, including the "phenomenal" performances of second-row siblings Richie and Jonny Gray, and the first Test starts for props Allan Dell and Zander Ferguson.
"It is the best I have seen Richie play for a considerable period of time. And it isn't a one-off performance from Jonny - it is every single week, it is incredible," said the former Wales hooker.
"I thought the props stood out really well, and some of the stuff they did outside the set-piece was excellent. They really made a contribution."
But Humphreys acknowledged that most of Scotland's post-match debrief will focus on their failure to close out victory.
"It is not about learning to close a 20-point gap, but trying to close a one-point gap," he noted. "You are up against a very good team who have been together for a long period.
"We need to close out one of these tough games. Once we do that, the cloud lifts and everything becomes a little easier. But the players are working very hard on that.
"Every time we come together we seem to be growing and becoming more confident in what we are trying to do.
"It is about trying to keep on that journey and hopefully by the time the Six Nations comes around, we are making significant steps to mounting a really good campaign."

Scotland will be a better team come next year's Six Nations if they learn to close out tight games, says fly-half Finn Russell.
